Yup, now you touch one core problem why Linux in desktop cannot get to masses — too much fragmentation. Next to unlimited chain of options and preferences, many of which even lead to severe incompatibility issues.
Ubuntu some decade or two ago looked promising ”one distro to rule them all” but seems to have turned to shit since.
If you look at Windows or macOS, it’s basically just a version or two to choose from, and the most common one suits 90% or more.
The same should happen in Linux world too. If an ”easy install tool” like described above would offer just ~5 most common distros, in their most common variant, it would still be a tremendous step forward.
If someone is knowledgeable enough to have strong distro pref, or knows that they need a certain system component, they most likely are not the target audience anymore as they can handle a manual install too. The target user may not even know there are different distros, and will just pick the ”Linux version” based on a screenshot that looks familiar or interesting.
So IMO; no options other than the absolutely critical ones (like to dual boot or not). There shouldn’t be more than maybe 3 big things the user has to decide themselves, for everything else the Linux community as a whole MUST be able to take a hard look at themselves and decide what are the most viable, compatible and best supported branches, and unite behind those.
I disagree. Sure, they are able to stick the drive to machine and use some easy tool (would need to be easier than Rufus) to write some data to it.
But then comes a big hurdle if USB boot is not the default: What is BIOS/UEFI? What key to press to get there? When do I press it? What are these text things? How do I navigate here? What exactly should I change? What is what of these drives listed? How to change the order? How to save? (Have witnessed this struggle a dozen times)
And IF they get through that step, then depending on distro they have very different kind of installation UI, all sorts of options they know nothing about, and they no longer have their browser and guide page open that they had when they started the operation.
We should not merely target the ”average person” but also, to a degree, the dumb masses below them. Look how simple the Windows 10 to Windows 11 installation has been made, there really is no way you can mess it up. If I remember correct, even upgrading from 7 to 10 was just: download ISO, double click to mount it, run setup.exe, click next a few times, and let it reboot and do its thing.
